Lot 279 - 1943 Bendix-Stromberg pressure injection carburettor
|Estimate||£1,900 - £2,300|
The first Rolls-Royce Merlin engines used a SU carburettor; however, the Merlin's float controlled carburettor meant that both Spitfires and Hurricanes were unable to pitch nose down into a steep dive. The contemporary Bf 109E, which had direct fuel injection, could 'bunt' into a high-power dive to escape attack, leaving the pursuing aircraft behind because its fuel had been forced out of the carburettor's float chamber by the effects of negative g-force. RAF fighter pilots soon learned to 'half-roll' their aircraft before diving to pursue their opponents. Further improvements were introduced throughout the Merlin range, in 1943 saw the introduction of a Bendix-Stromberg pressure carburettor that injected fuel at five pounds per square inch through a nozzle directly into the supercharger.
This Stromberg pressure injection carburettor is regarded as new old stock as it has never been used, the carburettor is complete with all the correct linkages and would bolt straight onto Rolls-Royce Merlin type 66, 70, 76, 77 and 85 engines and the Packard built Merlin type 224, 225 and 226 engines.
